Stefano Daino has announced that version 6.1.1 of DSP-Quattro, an application for Audio File Editing, Audio CD-ROM Mastering and DDP Import/Export, Plug-ins Hosting and Batch Processing for macOS, is now available.
New features since 6.0:
- DSP-Quattro is now fully compatible with macOS 26 Tahoe.
- New on the Batch Processor: added the possibility to set, update or clear CD-Texts processing files.
- New on the Audio Editor: added a command on Processing menu to "Change Length & BPM" which is able to produce results with the extreme precision of the single sample. Very useful also when resizing wavetables to use on software or hardware synths.
- New on the Audio Editor: added a button on the transport control to play backward the audo file.
- New on Mixer: now the Audio Editor and File Players channel strips have their own pitch controls and buttons to play the audio file backward.
-
New: the advanced VU-Meters floating window, including LUFS and TruePeak measurements, is now available not only as an option on each Channel Strip, but also as a built-in plug-in to put on any insert FX Chain.
-
The AudioCDLayout is very much more responsive.
- Several other minor bugs have been fixed.
